PIPE FITTING AND BOWL ASSEMBLY Victor A. Hofimann, Harvey, Ill.Application October 1'7, 1938, Serial No. 235,317

8 Claims. (Cl. 4-252) This invention relates to an improved. pipePositioned at the outermost end of the horifitting and bowl assembly.The fitting is espezontal pipe 58 and extending upwardly thereciallyadapted to support and provide an outlet from is a pipe 20. The upperportion of the pipe for a stack hung bowl. is turned upon itself to forman inverted U or a One of the principal objects of advantage and siphon2! and thence forwardly as is clearly importance of the device of thisinvention reshown in the drawing.

The flush pipe 46 passes through the opening 36 in the securing plate 32and is held in water tight engagement with the opening 44 by drawing thegland 50 against the annular shoulder 48 by means of the bolts 52 whichengage the threaded apertures 54 in the gland 50.

It will be apparent that the flush pipe connection as well as thedischarge connection between the bowl and siphon are made from the frontof the device. The necessity of providing a working space in the rear ofthe fitting for assemblin the parts is entirely eliminated.

Inthe operation of the improved pipe fitting and bowl assembly of thisinvention, a stream of water is directed through the jet 26 and upwardlyinto the siphon 2! slightly in advance. of admitting water into the bowl42. A siphon action is thus created and the water level in the bowlraises but slightly, if at all, as the water enters the bowl.

It will be apparent from the foregoing that herein is provided a stackhung bowl and pipe fitting assembly which is sturdy, rugged and may beeconomically produced. It is to be noted that the improved device ofthis invention leaves the fioor space directly beneath the bowl entirelyunobstructed. The clearance between the bottom of bowl and floor isexceptionally great.

It will also be apparent from the foregoing that herein is provided adevice of the kind referred to, the siphon and soil pipe of which may becompletely concealed within a conventional wall. Additionally, theimproved device does not require working space in the rear of thestructure for assembly.

Moreover, because the discharge connection is below the water line,leakage of gas through this joint into the partition or wall of abuilding in which the device is used is positively prevented.Additionally, the improved bowl of this invention requires from 4 to 6inches less space from the wall than a conventional bowl. Also the bowlmay be flushed with either an automatic valve or a tank.

It will be apparent to those skilled in the art to which the deviceappertains that numerous changes and alterations in construction anddesign may be made all without departing from the spirit or scope ofthis invention. Accordingly, it is understood that the patent grantedhereon is not to be limited to the preferred embodiment here disclosednor in any other manner except as necessitated by the terminology of theappended claims when given the range of equivalents to which they may beentitled.

6. In combination with a stack hung bowl having a substantiallyhorizontal discharge passageway, a pipe fitting including a plate havinga portion adapted to be attached to the discharge passageway of saidbowl, the opposite end of said fitting comprising a normally verticalstack, means preventing the leakage of sewer gas through the Joint inthe discharge passageway, said pipe fitting including a siphon ofconstant length intermediate the ends thereof, means operable throughsaid plate for cleaning said siphon, means for admitting a flushingliquid into said bowl, and means for directing an auxiliary streamupwardly into said siphon.

'7. A pipe fitting including a trap, a stack and vent pipe, a securingplate forming an integral part of and being a terminal of said fitting,said stack comprising the opposite terminal of said fitting, said trapand said vent pipe being permanently secured to said stack, and a jetopening into said trap in an upwardly disposed direction.

8. A pipe fitting including a trap and vent pipe, said trap and ventpipe being adapted to be concealed within a conventional partition, thelength of the pipe forming said trap being fixed, a securing plateforming an integral part of said fitting, a plurality of anchor boltreceiving recesses in said securing plate, and a jet opening into saidtrap in an upwardly disposed direction.
